A display apparatus having an object-oriented 3D sound coordinate indication is disclosed, in which sounds are outputted from a speaker positioned matching with a coordinate of an object in a matrix speaker apparatus formed of a plurality of small size speakers disposed behind a display apparatus in cooperation with an object content displayed on a display apparatus screen. The display apparatus having an object-oriented 3D sound coordinate indication comprises a center channel decoder which receives an audio signal corresponding to a center channel speaker among the audio signals outputted from a decoder of the surround speaker system and separates into sound sources based on an object; a center channel matrix for setting the coordinates of sound sources based on the objects separated by the center channel decoder; a matrix amplifier for amplifying an output sound of a speaker matching with each coordinate value of the sound sources based on the object; and a plurality of speakers which are arranged in a matrix shape behind the display monitor, whereby sounds are outputted through the speakers corresponding to the coordinates of the objects displayed on the display monitor.
